Hey there kenosis. Sorry to bother you again. SO the program is no longer giving me error messages, but the pushing to the arrays here:

  push @activline, "$1 | $2 | $activ{$1} \n" if $activ{$1};
    push @antioxline, "$1 | $2 | $antiox{$1} \n" if $antiox{$1};
    push @toxinline, "$1 | $2 | $toxin{$1} \n" if $toxin{$1};

isn't working properly. For example I selected a specific number from $activin, which was in $uniprot, but it wasn't in the final output. So @activline, @antioxline and @toxinline are much smaller than they should be. So a lot of the data that is supposed to be in the output is not there anymore. I tried testing with this:

if ($1 eq "E7F888"){print $2;}
[download]

and it gave me the correct $2, I tried this too:

next unless /(E7F888)\s+.+=([^\s]+)/;
 push @activline, "$1 | $2 | $activ{$1} \n" if $activ{$1};

print @activline;

and it printed the correct thing. But if I removed the tests i put, and ran the normal code, E7F888 is not in @activline. Is there anything I could do to figure out what's wrong with my code? Here's it again.

#!/usr/bin/perl
use Modern::Perl;
use File::Slurp qw/read_file write_file/;

my $uniprot     = 'uniprot-ACN';
my $activin    = 'Activator-PFAM.txt';
my $antioxin = 'AntiOxidant-PFAM.txt';
my $toxinin= 'Toxin-PFAM.txt';




my $activout = 'ActivACNPF.txt';
my $antioxout= 'AntioxACNPF.txt';
my $toxinout= 'ToxinACNPF.txt';
my @activline;
my @antioxline;
my @toxinline;

my %activ  = map {s/\.\d+//g; /(.+)\s+\|\s+(.+)/ and $1 => $2 } grep /
+\|\s+\S+/, read_file $activin;
my %antiox = map { s/\.\d+//g; /(.+)\s+\|\s+(.+)/ and $1=>$2; } grep/\
+|\s+\S+/,read_file $antioxin;
my %toxin  = map { s/\.\d+//g; /(.+)\s+\|\s+(.+)/ and $1=>$2; } grep/\
+|\s+\S+/,read_file $toxinin;
#if (exists $activ{"E7F888"}) {
#print $activ{'E7F888'};}
#else {print "LOL";}
for ( read_file $uniprot ) {
 next unless /(.{6})\s+.+=([^\s]+)/;
   # if ($1 eq "E7F888"){print $2;}
    
    push @activline, "$1 | $2 | $activ{$1} \n" if $activ{$1};
    push @antioxline, "$1 | $2 | $antiox{$1} \n" if $antiox{$1};
    push @toxinline, "$1 | $2 | $toxin{$1}  \n" if $toxin{$1};
 
}
print @activline;
write_file $activout, @activline;
write_file $antioxout, @antioxline;
write_file $toxinout, @toxinline;

THanks so much.
